You may come to realize that you are not going to get much better with just a single SATA drive. 5.8-5.9 is about as high as they go.
About the only way to increase it significantly is with either a RAID configuration or an SSD.
The SSDs score so high by comparison that even the RAID0 configurations only get into the 6.x range.
P.S. What video card are you using?
